Charlie and Craig Reid teamed up with Kay and Lucas for the song

Scottish duo The Proclaimers have gone to the top of the singles chart thanks to a charity version of their 1988 hit (I'm Gonna Be) 500 Miles.

The Fife double-act teamed up with comics Peter Kay and Matt Lucas to re-record the song for Comic Relief.

Kay and Lucas feature in their Brian Potter and Andy Pipkin personas.

In the album chart, Enter Shikari - who came fifth in the BBC's Sound of 2007 poll - enter at number four with their debut, Take To The Skies.

Released on their own Ambush Reality label, the band's mix of rock and dance beats saw them become only the second unsigned band to sell out London's Astoria venue, after The Darkness.

Take That regain their top spot in the album chart, swapping places with X Factor runner-up Ray Quinn.

The Proclaimers' chart success is their first since 1994, and comes nearly 19 years after the release of the original track - which itself is back in the chart, at number 26.

With Sugababes and Girls Aloud's cover of Walk This Way falling to number two, the top two positions in the singles chart are taken up by Comic Relief tracks.

Avril Lavigne's Girlfriend enters the chart at number three, while Newcastle's Maximo Park rise to number nine with Our Velocity.
